    BIOLOGICAL FEATURES OF ISATIS TINCTORIA AND THE QUALITY OF ENSILED BIOMASS UNDER THE CONDITIONS OF THE REPUBLIC OF MOLDOVA
    (CEP USM, 2024) Guţu, Ana; Ţiţei, Victor; Ababii, Alexei; Gadibadi, Mihail; Dorofte, Veaceslav; Cozari, Sergiu; Gudima, Andrei; Andreoiu, Andreea Cristina; Tod, Monica; Cîrlig, Natalia; Mazăre, Veaceslav; Mazăre, Romina
    We studied some biological features and the quality of the silage prepared from Isatis tinctoria plants cultivated in the experimental plot of the “Alexandru Ciubotaru” National Botanical Garden (Institute), Chisinau, R. Moldova. In the second growing season the local ecotype of Isatis tinctoria was characterized by fast growth and development rate, reaching 118-147 cm in height, with a content of leaves and inflorescences of 57%. I t has been determined that the dry matter of ensiled mass from the local ecotype of Isatis tinctoria was characterized by 196 g/kg CP, 160 g/kg ash, 314g/kg CF, 335 g/kg ADF, 521 g/kg NDF, 37g/kg ADL, 298 g/kg Cel, 201g/kg HC with nutritive value 628 g/kg DDM, 10.16 MJ/kg ME, 6.18 MJ/kg NEl and RFV=112, this fact indicates an optimal quality of the silages prepared for ruminants. The biochemical methane production potential of Isatis tinctoria silage substrates reached 361 L/kg VS. The ensiled biomass from the local ecotype of Isatis tinctoria can be used as alternative forage for ruminant animals, or as substrates in biogas generators for the production of renewable energy.

    SPECII DIN GENUL REYNOUTRIA HOUTT. DIN COLECȚIILE GRĂDINII BOTANICE NAȚIONALE (INSTITUT) „ALEXANDRU CIUBOTARU”
    (CEP USM, 2024) Cîrlig, Natalia; Ţiţei, Victor; Ţiţei, Victor; Ababii, Alexei; Gadibadi, Mihail; Doroftei, Veaceslav; Andreoiu, Andreea Cristina
    The species of the genus Reynoutria Houtt are described in the article. grown in the collection of fodder, honeydew and energy plants from the “Alexandru Ciubotaru” National Botanical Garden (Institute). The purpose of the research is the description of the phenological spectrum of Reynoutria sachalinensis and Reynoutria japonica plants, the study of the biological peculiarities of growth and development of the plants in the climatic conditions of the Republic of Moldova. The harvested biomass can be used as feed for animals or as sub strate for biomethane production.

    THE ASSESSMENT OF THE NUTRIENT CONTENT IN THE PLANTS OF THE HYBRID SORGHUM BICOLOR X SORGHUM SUDANENSE HARVESTED IN DIFFERENT DEVELOPMENT STAGES
    (2023) Ţiţei, Victor; Cîrlig, Natalia; Coşman, Valentina; Guţu, Ana; Mocanu, Natalia; Cozari, Sergiu; Teleuţă, Alexandru; Garştea, Nina; Coșman, Sergiu
    The article presents the results of the research aimed at evaluating the nutrient content in the leaves, stems and panicles of the hybrid sorghum x Sudan grass "ȘAȘM-4" plants harvested in different development stages. It has been determined that the leaves have a higher content of crude protein, crude fat, carotene, ash, calcium and phosphorus; the stems have a high content of crude cellulose, nitrogen-free extract and sugar; while the panicles are rich in starch, with high energy value. During the growing season, in all component parts, the content of dry matter increases, the concentration of proteins decreases and the content of cellulose and nitrogen-free extract essentially increases.
